Running SteamOS on separate SSD on my PC. Been running fine with no issues for months now. Randomly today I had been running in windows as some games do not operate on Steam yet and when I went to reboot and boot back into steam it is stuck on boot loop. I am unaware of any patches or changes today on the operating system to potentially have caused this. I know there was a update in the last day or two but I had run steam since then.
Behavior: I see mobo post screen, see the quick prompt to hit F11 to change boot order (steam OS is #1, so I do nothing) screen turns black and I expect it to start loading into steam (on other screen, I have two screens) and instead it just loops back to beginning and I see mobo post again.
I CAN hit F11 and boot into windows with no issue. I did verify that secure boot hadn't turned back on. I have not changed any system level configs recently so I am unaware of what caused the boot loop.
Questions: How do I recover? I suspect the bootloader is stuck on some thing and just needs to get past that. I did run a test on the nvme drive and no issues.
I'm on a AMD 9850x3d and a 9070xt so drivers shouldn't be an issue. Again, had zero issues for a while now running this way.
